PrenatalDetect RHD

Offer pregnant women targeted treatment with our fetal Rhesus D service

Our PrenatalDetect RHD service offers a highly sensitive and accurate test for non-invasive screening of fetal Rhesus D (RhD). We believe in providing timely insight to physicians so they can provide pregnant women proper autonomy for their treatment. With our test results, physicians ensure that only mothers needing anti-D prophylaxis, receive it.

Benefits of test

Rh disease occurs when there is a mismatch in the genetic expression of the RHD gene between mother and fetus. People who lack RhD on their red blood cells are RhD-negative. Pregnant women can produce antibodies against RhD if they are exposed to RhD-positive red blood cells. This immune response destroys red blood cells produced by the fetus and results in anemia in the fetus, causing several complications and potential fatality.

To combat this, universal anti-D prophylaxis treatment has been implemented for Rh-negative mother. However, 40% of Rh-negative mothers are carrying an Rh-negative fetus and are exposed to unnecessary treatment with potential risks.1-2

Personalized treatment

We understand that a one-size-fits-all approach does not fit with modern, personalised treatment. We help you empower your patients on deciding the testing and treatment they want during pregnancy. Our modern approach helps avoid unnecessary universal treatment. Provide your patients with all the results they need to make informed decisions about their treatment.


Sample collection from gestation week 10 using a single EDTA blood tube is all that is needed. No invasive fetal blood sampling is required, thereby avoiding exposing the fetus to risks associated with conventional invasive sampling.

Saves time

Patients can avoid multiple visits to the care provider for injections. We understand that many patients spend a lot of time and money to reach a care center for treatment. Anti-D prophylaxis can involve the administration of multiple doses for patients, requiring visits to a care center. With our test, physicians can evaluate whether this treatment is necessary or not, and therefore avoid unnecessary travel for their patients.
